The actual most important thing a fighting game has to do, is attract players. If you have two fighting games, a "good" game with no players, and a "bad" game with 3k concurrent players on steam

The "bad" game, is the better option. Its intrinsically more conpetitive, its intrinsically more fun.

If the game is ugly, the fans will fix it with fan art, if the game is unbalanced, patches will fix it, if the game is too easy, more people will play
